07:56 AM EDT, 10/14/2025 (MT Newswires) -- CarMax ( KMX ) was Smart Insider's stock pick of the week after the company's non-executive Mark O'Neil purchased $500,000 worth of company shares for $46.21 apiece on Oct. 2, raising his ownership by 78%.

O'Neil previously bought $252,000 worth of company shares at $93.40 per share in September 2020, which was ''well-timed,'' Smart Insider said in a Tuesday note.

Independent Director Mitchell Steenrod also acquired $91,000 worth of company shares on October 2, the note said, adding that Steenrod purchased $85,000 worth of shares at $65.49 apiece in April, which was "poorly timed," but it's "encouraging" that he is "averaging down" with another stock buy.

These are "notable" buys after stock price weakness since CarMax ( KMX ) posted earnings on Sept. 25, according to the note.

Smart Insider ranked the stock +1, indicating a strong positive signal, on October 7.
